Question

a train leaves a city heading west and travels at 50 miles per hour. three hours later, a second train laeves from the same place and travels in the same directionat 65 per hour. how long will it take for the second train to overtake first train?

Answer 1

To do these kind of questions, you have to ask yourself, what quantities are equal, so I can set up an equation.

When the second train overtakes the first, aren't the distances traveled by each equal ?

The slower train went t+3 hours, while the faster train only went t hours, right?

You know their rates, so can you find the distances they went?

let me know how you made out.
